	The formation of the pedosphere, or pedogenesis, requires multiple factors, taking from the four different planetary subsystems, or spheres. The air above the soil, living organism interactions, water inside, on top of or below the soil, and unconsolidated, superficial rock deposits. Layer formation begins with mechanical and chemical weathering of minerals in order to form [[regolith]]. Organic reactions from biological sources such as [[lichen]] and [[moss]] increase the rates of [[decomposition]] of the initial materials. Once the soil material has accumulated, water enters the system causing nutrient movement and ion exchange. The geochemical makeup of the soil then moves away from the parent material and reflects more of the biological processes taking place. The time it takes for this process to form one inch of soil is 500 years.[2]		The formation of the pedosphere, or pedogenesis, requires multiple factors, taking from the four different planetary subsystems, or spheres.

	The gaseous exchange between the pedosphere and atmosphere is at all times in equilibrium. Carbon dioxide is the most commonly exchanged gas between the spheres because of high microbial CO2 production and CO2 release from [[root hairs]]. This also causes higher than average bicarbonate (HCO3-) concentration in soil waters. Other exchanges between the two include rainfall and sedimentation via wind erosion/weathering.[4]		The gaseous exchange between the pedosphere and atmosphere is at all times in equilibrium.

	Lichens, the [[pioneer species]] of soils, begin soil production processes with the secretion of oxalic acid into the regolith. Organic acids from plants are released into the soil layers and perform a process known as [[chelation]].[4] These acid types include acetic acid, citric acid, phenolic acid, humic acid, and fulvic acid. Other inputs from the biosphere include [[earthworm]] soil activity, in which they improve fertility by forming [[humus]] in soil layers. Animal waste and animal decomposition also add nutrients such as nitrogen and phosphorus to the pedosphere.

	As water enters the soil parent material, it transports matter around horizontally and vertically throughout the pedosphere. Water is consumed by fauna inside the pedosphere, allowing for the biosphere to begin its processes within the soil. Higher amounts of soil water are linked to higher rates of chemical weathering, and soil water volume shapes the formation of soils.[3] Different environments house different amounts of precipitation and groundwater, leading to stark differences between their [[clay]] types, e.g. rainforest soils are high in water causing high amounts of chemical weathering, leading to higher decomposition rates and the inability for [[podsolisation]] to take place, leaving mobile metals to form oxides. This gives tropic soils brighter reddish colors.		As water enters the soil parent material, it transports matter around horizontally and vertically throughout the pedosphere.

			Lithospheric interactions form the base for pedosphere creation, and lithosphere composition determines available material for soil formation. As rock material is weathered and regolith forms and builds up, it allows for lichen to begin further breaking down of material.
